i' o @5E 'whom 'it muy concern a su sidi,

it 4known that il, .ions l. (fiori-nun, "ect of the King; oli Greet Britain, rcet Perth Road, in the Province ot' Canada, here invented certain new end useful improvements in lleiephoneell Recorders; and i do hereby declare the oliorving to a full., clear, and

enact description of the invention, such as wilt enahle others sinned in the art to which it eppcrteins to :make and use thc same.

This invention relates to recording Adevices and has speciai ence to a.l device adapted to he used in congui'iction 'with telephones of either the wail or sta-nd type, for recordlng the number ot calls used. is Weld irnovfn among the subscribers oi? telephone companies that when one has limited phone servicelit is extremely dcsirable to be able to keep account of the nuniher of oeils used Yin 4order that the prescrii be carelessly' e):- cceded and in order to check up the report )ed number may not et the telephone company. Devices `for this purpose have been designed and have s many disadvantages that they have not corne' into popular use. .The disadvantage oi many ot these devicesis that -cverv time the receiver hoolr is moved ay call regis tered which shouid not be the case as a subscriber has frequently to more the receiver hook repeatedly to 4attract the 'attention of the central operator. To .overcome these disadvantages this im'ention` has been de the recordoperated by hook at the signed and so constructed that ing device may or may not be the increment oi the receiver `will of the operator.

An important object is to provide a device of' this character which may be quickly, readily, and adjustably connected with any style of telephone.

Other objects and advantages, such as simplicity, cheapness, efiicienoy in operation, durability in service, and the general imnroveincnt of the art Will be carefully brought out in the 'following description and illustrated in the laccompanying drawings, in which,

Figui-e1 is a` 'front elevation of a telephone with my device applied thereto, Fig. i2 is a side elevation thereof, Fig. 3 is a horizontai section helow the transmitter, and, Fig'. t is e detaii perspective vievwot the ciips and supporting bracket.

Referring more particulariy t e cre-vr ings, the numeral designens 'any Wel?. known or preferred type ot telephone com prising the usual hase 6, standard i. carry ing; the transmitter 8 and having the i r ally extending receiver hoolr 9A f i. to support the receiver 1G. fill these 'parts :rre old and Well known and consequently no further description oi?v thein .vili be made.

My novel recording device comprises' tivo members, one attached ,to the receiver 'l0 and the other attached to the standard i", each of these members being adapted. to coperatie. 'if he member disposed upon the standard 7 comprises a pair oii circuiar ciips 1.1 provided with ears 12, the clips 1l. being spaced apart upon the standard 7 and cou.- nected by `a .bar 13 having a slot 14 formed therein for the reception of the stem i 'secured to the casing '16 of' a recorder i7. B v this means it will he seen that the recorder may be moved vertically upon the bar 1S and be clamped in any desired position thereon by Ineens of thumb or Wing nut 1S engaging the screwthreaded end of the stem 15.

The recorder 17 is operated oy means ot a laterally extending arm 19 which entends I into the casingq of the recorder and actuetes the step-bystcp ratchet movement for mov ing the hands 20 upon the graduated dial 21 of the recorder. he dial 21 is divided preferably into a hundred graduations, over' which the larger of the hands 20 travels, moving one graduation every time the arm 19 is moved downwardly. iin orderto record a very large number oi calls the dial 21 may be provided with another set of ltgiaduations traveled over by the smaller of the 'hands 20, one complete revolution of the larger hand moving the smaller hand one graduation. When the recorder 17 is mounted upon Ithe bar 13 and properly adjusted thereon, the arm 19 will extend in an upwardly and inclined direction substantislly parallel with the receiver hook 9.

ln order 'that the arm 19 .may be actu ated for operating the recorder, li provide a member 22 .upon the receiver 10. The member 2Q comprises a ring Z3 having its ends separated and provided with lugs 2li betweenwhich is' disposed a block 25 conforming in contour to the lugs 24:, the lugs 24 and block 25 beingsecured together by a screw Q6 passing through them and cianoI tit" longitudinali fore no recording ing the member securely 'adjacent the smaller end of the receiver 10. The lugs 24 the position shown in the drawings, the 'receiver h'oolrlv 1s in its lowest position, the arm -19 .is in its lowest position, and the phone is phone 'call'is made* and the receiver l0 removed. from the hook 9 the arm 19 or" the recorder will move upwardly by virtue of a springq contained within the recorder. When it is. esired to ring od. or sever connection with the 'teiephone line, the receiver 101s placed uponV thehook 9 in the usual manner, with the lugs 24 facing toward the u er "of the. phone, ywhereupon the weight fthe receiver will depress the hook 9, as is Well known, and the lugs 24, by virtue of vtheir engagement with the arm i9, will move the arm 19 downwardly, causing the recorder 17 to operate and movingthe larger hand one graduation. If it is not desired to record the call, as for instance, when a wrong numbery is given by the contrai operator or in any other instance in which the call would not be charged for, the receiver A`vvruld be placed upon ,the hook with the lugs 245 facing in the opposite direction so that they would not engage the arm 9, whereupon, 'of course, the recorder would not be o erated. If it is found necessary to move tliie hook 9 up and down repeatedly tp attract the attention of the central operator, the arm 19 would not he moved, and therewould be done. l

By providing the clips 1l clamped upon the standard 7, the recorder and its associated parts may he readily adjusted vertically upon the standard and, furthermore,

her of calls over inl readiness to be used. When the ture, 1n

License kthe provision of the slot 14 in thebar 13 enables the recorder to be adiusted independently upon the bar 13 so that the arm 19 will extend in the proper direction and at the correct height to be actuated when engaged by the lugs on the receiver.

From the foregoing it will be apparent that thus have provided a novel, simple, and' ehcient means for recording the numa telephone and at the same receiver hook to be moved independently of any recording time allow the absolutely action.'

It will be readily understood that I m'ay make various changes in the form, construction, and arrangement of parts without departing tion or limiting the scope of the suhjoined claim, as for instance I may omit the clips and provide lugs upon the ends of the bar 13 whereby the bracket may be attached to a Wall phone instead of a phone having a tubular standard.

Having thus described my claim is An attachment for desk telephones, comprising' a longitudinally slotted plate having terminal clamps for engagement with the standard of the telephone, and a recording device having at one side a stern slidably disposed in the slot of the plate and means for holding the stem at any point of its sliding movement, said recording de vice including an actuating lever of a length to be positioned in the path of movement of a lateral extension of a receiver, as the receiver is moved into engagement with the hook that projects from the standard.

invention, what from the spirit of the inven-' In testimony whereof, I aiix my signal the presence of two Witnesses.
